How to use E26 screw cap gauge(1)E26 Lampholder General Regulation (7006-27D-3) Purpose: Used to detect the smallest size of lampholder thread size and lampholder length.How to use the E26 lamp holder pass rule: a) Screw the lamp cap into the gauge, which can be screwed in smoothly, indicating that the lamp cap meets the size requirements of the lamp cap thread; b) Screw the lamp cap fully into the gauge to see if it can touch the X surface, if it can, it means that the length of the lamp cap meets * Small size requirements. c) When unscrewing the lamp head from the gauge, at least......
Identify BVR, BV and RV wires and cables？
2020-04-30 [ Industry News ]
1. The difference between BVR, BV and RV wire and cable.1. The difference between B and R, the former is a cable (wire) for fixed wiring, and the latter is a flexible wire for connection.2. The difference between BV, BVR and RV is the conductor structure. In general, BV uses the first conductor, BVR uses the second conductor, and RV uses the fifth conductor.3. BV is generally a single core wire with a hard conductor; while BVR is a soft conductor; the two resistance values are the same. The RV is softer than them, and the insulation requirements are different.Guangzhou Gaaye Electronics Co., L......
Comparison of copper core cable and aluminum core cable
2020-04-29 [ Industry News ]
Copper core cable has advantages over aluminum core cable:1. Low resistivity: The resistivity of aluminum core cable is about 1.68 times higher than that of copper core cable.2. Good ductility: the ductility of copper alloy is 20 ~ 40%, the ductility of electrical copper is above 30%, while that of aluminum alloy is only 18%.3. High strength: the allowable stress at room temperature, copper is 7 ~ 28% higher than aluminum respectively. Especially the stress at high temperature, the difference between the two is even further.4. Anti-fatigue: aluminum is easy to break after repeated bending, but......
Do you know the difference between cable and fiber optic cable?
2020-04-28 [ Industry News ]
1. The difference in material: the cable uses metal material (mostly copper and aluminum) as the conductor; the optical cable uses glass fiber as the conductor.2. The difference between transmitted signals: electric signals are transmitted by cables; optical signals are transmitted by optical cables.3. Difference in application range: cables are mostly used for energy transmission and low-end data information transmission (such as telephone); optical cables are mostly used for data transmission.Therefore, the working principle, structure, material, transmission signal and application range of ......
